Title:
METHOD FOR MANUFACTURING POLARIZER
Document Type and Number:
WIPO Patent Application WO/2013/051554
Kind Code:
A1
Abstract:
This method for manufacturing a polarizer is provided with the following steps, in this order: an adhesive application step in which an active-energy-ray-curable adhesive is applied to one surface of a transparent film or transparent films or one or both surfaces of a polarizing film; a bonding step in which a layered body comprising the transparent film(s) layered to one or both surfaces of the polarizing film with the aforementioned adhesive interposed therebetween is subjected to pressure so as to bond the transparent film(s) to the polarizing film; and a first active-energy-ray exposure step in which the adhesive is cured by exposing the aforementioned layered body to active-energy rays while said layered body is being conveyed in close contact with a roll rotating in the conveyance direction. The cumulative amount of ultraviolet-ray (UVB) exposure in the first active-energy-ray exposure step is between 10 and 185 mJ/cm2, inclusive.
